Issue Tracker "Build Query" Doesn't URL Encode Ampersand (BB-3351)

For instance, if you filter by a milestone named "XYZ & ABC", the URL produced for the query is

https://bitbucket.org/me/myrepo/issues?milestone=XYZ%20&%20ABC&status=new&status=open

The extra ampersand unsurprisingly messes up the query and the system spits out:

amp;%20ABC: "undefined" milestone: "XYZ " status: "new" or "open"

If you manually alter the URL to the following (URL encoding instead of HTML escaping the ampersand) it works properly:

https://bitbucket.org/me/myrepo/issues?milestone=XYZ%20%26%20ABC&status=new&status=open
