CTest integration not picking up test names on first compile

### Brief Issue Summary

I have a project where I am managing tests through Catch2. The CTest integration can successfully find, run, and display the results from my tests, but I'm facing an odd issue where it only works on the second compile of the project.

The first compile and run of Ctest finds no tests because instead of running the tests with a command of the form:

`ctest -jxx -C Debug -T test --output-on-failure -R ^my_test_name-buildid`

it instead runs

`ctest -jxx -C Debug -T test --output-on-failure -R ^my_test_name_NOT_BUILT-buildid`

The build itself actually looks fine, running `ctest` with no arguments in the build directory will run all the tests.

What's odd is that if I recompile (say by selecting a different build variant) and recompile/retest, changing nothing else, it will correctly pick up and run all the tests.

I can't figure out where the extension is picking up the test names, for example grepping for NOT_BUILT in the build directory returns nothing.

Reproduce the first-compile CTest run in the build directory and compare its generated test filter with the second compile. Trace the CMake Tools CTest integration that produces the `ctest -R` command; done means the initial compile uses the test name rather than the `_NOT_BUILT` suffix and discovers the tests consistently.
