Fix removal of whitespace in ignored/required tags

[Krenair]

This replacement was presumably to handle spaces following commas, but it also got important spaces in the middle of tags.

Bug: T155333

[se4598]

if I'm reading this correctly, this only gets one whitespace at the first position.
And as I like using framework functions instead of writing own, I would use the following x = x.replace("\n", "").trimmed(); (I left the replace b/c if somehow a strange '\n' is inside a string based on original code)

Why do you want to get rid of all whitespace on both sides of each tag?

[se4598]

Are tags possible that start or end with spaces? If not and this is directly from user input (whether user config or input field, why shouldn't it removed for usability? Previously the spaces would get removed.
Yeah, it may be a little bit speed inefficient most of the time, but this shouldn't be a location and magnitude where this matters.

Disclaimer: Despite marked as org 'member', I'm just doing code reading here, I don't know/can't look up where the function is called from, as haven't looked at huggle and it's code for a long time.

I think that se4598 is right, one thing is that at some point, there could be whitespace on both sides, for example if someone edited their huggle3.css by hand and added there string like that "tag1, tag2 , tag3"

This is of course their mistake, but I like software that is more error-tolerant and thus user friendly :)

but it really is easy to fix I can do that myself, thanks for finding where the problem was
