Fixed issue boards not filtering when URL params are encoded
What does this MR do?
Filtering with a saved URL like ?label_name%5B%5D=test will cause Vue Resource to encode the already encoded param %5B%5D making the label_name filter actually send something like label_name%255B%255D=test. This fixes that by decoding it first before sending it off to the API.
