Special characters in filters don't reload properly

Hi there,

playing with filters I found that if I enter an email address in a text filter, when reloading the browser the ā€˜@ā€™ character is replaced by ā€˜%40ā€™, giving obviously wrong results in the dashboard. Other special characters give problems too, when reloading the web page.

I think this is a minor bug, but I also think it should be easy to fix :wink: Hope it helps.

P.S: Iā€™m using Firefox v49.0

sounds like a bug. can you enter it at github.com/metabase/metabase/issues/new?

thanks!
