Unable to run CTest in parallel

[Jepsson]

Brief Issue Summary

After updating to v1.18(from v1.17) I am unable to run our google tests using the "Run CTest" button in the status bar,

I am using a CMakePresets.json which looks like this:

"testPresets": [
        {
            "name": "unit-test",
            "execution": {
                "jobs": 16
            },
            "configurePreset": "unit_test"
        }
]

and also setting "cmake.ctest.allowParallelJobs": true

In version v1.18
Ctest command generated: /usr/bin/ctest -T test --output-on-failure --parallel 16 -j18 -R ^<big chunk of tests>
Output from command:

[ctest] RegularExpression::compile(): Expression too big.
[ctest] No tests were found!!!

In version v1.17
Ctest command generated: /usr/bin/ctest -T test --output-on-failure --parallel 16

other info
If I set "cmake.ctest.allowParallelJobs": false I can run the tests but they take ages to run(~1700 tests), and when running in parallell it takes ~4 seconds.
It also seems very strange that the extension adds a flag(--parallel 16) for my specified number of jobs in CMakePresets.json and also a flag(-j18) when setting allowParallelJobs to true.

@Jepsson Hi, we're having conversation about this regression in this issue as well: #3804. I'm going to close this one as a duplicate, but please see this comment and try to install the vsix (after renaming from a .zip), and see if it fixes your issue. If it does, then I'll create a merge a PR. Thanks!

@Jepsson Could you confirm that the vsix in that comment fixes your issue?

[Jepsson]

@gcampbell-msft I have installed the vsix and it works, thank you!
It's still a bit strange that the ctest command includes the "--parallel/-j" flag two times, i.e. /usr/bin/ctest -T test --output-on-failure --parallel 16 -j18
