Allow removing tags using -tag syntax also in Test Tags #5250
Description
Test Tags from *** Settings *** and [Tags] from Test Case behave differently when removing tags: while it is possible to remove tags with Test Case's [Tag] -something, Settings Test Tags -something introduces a new tag -something.
Running tests with these robot files (also attached):
__init__.robot:*** Settings *** Test Tags something-SomethingInSettings.robot:*** Settings *** Test Tags -something *** Test Cases *** -Something In Settings Should Be Empty ${TEST TAGS}-SomethingInTestCase.robot:*** Test Cases *** -Something In Test Case [Tags] -something Should Be Empty ${TEST TAGS}
gives the following output:
> robot .
