messageTray: fix url highlight

Review of attachment 178680 [details] [review]:

I came up with the same patch after the problem was mentioned on IRC, so I guess it's OK, though it definitively needs a more verbose commit message; for reference, this is what I used:

util: Fix regex used to match for URLs
 
Commit a65a0f03d49 changed the literal RegExp to a string-based
RegExp(). As backslashes are treated specially inside strings,
translating an expression as /\s/ to '\s' results in a faulty
regex of /s/, so escape backslashes where necessary.
