Filter test files using "includes" instead of "equals"

[MZanggl]

Proposed changes

Testing a single file currently requires you to specify the entire file name, including the file extension. E.g.

adonis test -f 'UserService.spec.js'

With this fix in place, simpy UserService or even User would be enough. This then nicely aligns with the way grep works

Hey @MZanggl!

Thanks for your contribution! Could you please add some tests that cover your change.

@thetutlage Do you believe we should consider this as breaking change?

@RomainLanz I just added tests. I moved the filter part to the cli so now all the filtering is together in one place and became easy to test.
