Restore ability to run single SLT file

[findepi]

Make it possible again to run single SLT file, even if it's name is a substring of other file(s).

For example, after the change, this command:

cargo test --test sqllogictests -- test_files/union.slt

runs union.slt file, but does not run pg_compat_union.slt.

The functionality was probably accidentally lost probably in #13936

I made a small PR to your branch to show the # of files tested, verifying that

cargo test --test sqllogictests -- union.slt

runs 2 files whereas

cargo test --test sqllogictests -- test_files/union.slt

runs 1 file.

I also verified that the sqlite tests ran without issues.

Thank you @findepi ! I verified this PR using #14359

BTW I think it is currently possible to run a single file. For example this will run both union.slt and pg_compat_union.slt.

cargo test --test sqllogictests -- union.slt

However, it only matches on the file name (not the entire path) so using test_files/union.slt does not work as you observe

I made a small PR to your branch to show the # of files tested, verifying that

LOL we did the same thing @Omega359

• Minor: include the number of files run in sqllogictest display #14359
