Cannot update a milestone title to a new phrase containing special characters

[aminlatifi]

I get error once I want to update a milestone title with a phrase which had parenthesis. It happens on checking milestone new title is unique in its campaign.
I reached to a solution like this in searching, both front-end and back-end

title
          .replace(/([-/\\^$*+?.()|[\]{}])/g, '\\$&')
          .replace(/^\s+|\s+$|\s+(?=\s)/g, '')}\\s*`,

But I am not sure the above solution works and should be tested.

@aminlatifi
Cant reproduce it, I changed my trace's name multiple times including parenthesis and it was ok

I had created the Test parenthesis (1) before

I had updated the regex in backend, but forgot to update the front. @mohammadranjbarz Please make it happen.
