[CLIENT] client shop champion filter

I tried to filter for Bard using 'Mage' but he wasn't listed although he's a secondary Mage. You can filter for Karma, for example, using either 'Mage' or 'Support' so i assume it's a bug in Bards case but a minor one. I wanted to report it nonetheless.

The steps to reproduce this are obviously easy: Go to the shop, then click the champions tab and check the mage filter and don't find Bard in the list.

Other champions might also have this problem but i didn't try.
