Removed marked for removal

[codeconsole]

@matrei any idea what is going on here?

@codeconsole Looking at the comment in the code, It looks like there was a problem with the src/main/resources/META-INF/grails.factories file being overridden by a version generated by the compileGroovy task.

So, apparently a grails.factories file is generated by the compileGroovy task and this workaround directly deletes it so it does not override the one in src.

Looking a the "Remove after 5.0.0.M2" TODO, it seems that this commit is meant to fix this, but the workaround here was never removed.

Maybe the fix, didn't work, or it was just forgotten to remove the workaround.
I'll try out the code later to see what it does.

When I tested this, removing this causes it to still fail. I had to leave these in the gradle files.
