Do not normalise tag names in View All Tags dialog

Framework Version: 2.8.7
Python: 2.7
Operating System: Win 7 Enterprise
Using RIDE 1.3

If I have tag:
TableCleanUp

on one test, and:
Table CleanUp

on another test, when I select Tools -> View All Tags, nothing happens. I hooked RIDE into an IDE, and got the following:

KeyError: u'Table CleanUp'

Start in robotide/ui/tagdialogs.py, especially _search_for_tags(), and reproduce the View All Tags action with the two distinct tag names shown in the report. Trace how tag names are stored before the KeyError occurs. Done means the dialog opens and displays both tag names without normalising them or raising the reported error.
