Neotest watch does not work in a large Go repo

[asfaltboy]

I've got a large repo with hundreds of packages, and thousands of files, and test watcher seems to not run any test on change.

Debug logs shows a lot of continuous messages such as:

Where the file names alternate between different files, and seem to be repeating. (note that 'registed' message is mis-typed in the actual code)

When saving a change in the test module, I see this emitted in the debug log:

Note: I shortened and obfuscated file/path to protect the identity of the code owner.
