rasa test should search for test files recursively in all sub-directories, not just under tests/

[koernerfelicia]

Rasa version:
2.2.4
Python version:
3.7.2
Operating system (windows, osx, ...):
OSX

Issue:
rasa test looks recursively for files prefixed with test_, but only in subdirectories of tests/. It should look recursively in all subdirectories.
rasa test core seems to look for these files in any subdirectory.

Command or request that led to error:

rasa test

@kalkbrennerei finally got around to making this. Could you add some comments if you have any? Thank you!

from our Slack discussion:
Lu:"I think rasa test and rasa test core are both using test.py::run_core_test internally but with different args"

[kalkbrennerei]

thanks @koernerfelicia! I think I have nothing to add 😃
but maybe I can mention this PR here. I think we decided to only accept test story files with test_ prefix, so with the fix of your issue the linked PR will become irrelevant if I'm not mistaken

I'll close my PR as well. @kalkbrennerei Do you know any specific reasons for the decisions or where we could find that? Seems like it addresses a code problem by causing friction for users.

@wochinge I think for 2.0 we wanted to enable the users to structure their projects the way they want to, so without restricting them to have a/only one tests folder. And therefore the tests must have the tests_ prefix. But it also doesn't seem ideal to me that this is causing friction to the users... This Thread seems to have a discussion about it, but not sure of the actual conclusion.
