Merge #17388: Add missing newline in util_ChainMerge test

3645e4ca0033bb6365f41ef710111780c139370f Add missing newline in util_ChainMerge test (Russell Yanofsky)

Pull request description:

  This was causing a lot of test cases not not be very meaningful because
  multiple configuration options were combined into one line.

  The changes in test output with this fix make sense and look like:

  ```diff
  - testnet=1 regtest=1 || test
  + testnet=1 regtest=1 || error: Invalid combination of -regtest, -testnet and -chain. Can use at most one.
  ```

  <!--
  Please provide clear motivation for your patch and explain how it improves
  Bitcoin Core user experience or Bitcoin Core developer experience
  significantly:

  * Any test improvements or new tests that improve coverage are always welcome.
  * All other changes should have accompanying unit tests (see `src/test/`) or
    functional tests (see `test/`). Contributors should note which tests cover
    modified code. If no tests exist for a region of modified code, new tests
    should accompany the change.
  * Bug fixes are most welcome when they come with steps to reproduce or an
    explanation of the potential issue as well as reasoning for the way the bug
    was fixed.
  * Features are welcome, but might be rejected due to design or scope issues.
    If a feature is based on a lot of dependencies, contributors should first
    consider building the system outside of Bitcoin Core, if possible.
  * Refactoring changes are only accepted if they are required for a feature or
    bug fix or otherwise improve developer experience significantly. For example,
    most "code style" refactoring changes require a thorough explanation why they
    are useful, what downsides they have and why they *significantly* improve
    developer experience or avoid serious programming bugs. Note that code style
    is often a subjective matter. Unless they are explicitly mentioned to be
    preferred in the [developer notes](/doc/developer-notes.md), stylistic code
    changes are usually rejected.

  Bitcoin Core has a thorough review process and even the most trivial change
  needs to pass a lot of eyes and requires non-zero or even substantial time
  effort to review. There is a huge lack of active reviewers on the project, so
  patches often sit for a long time.
