Fixed caching of user issues when having multiple Jira issues

Multi-instance fix for user issues

After #202, I found that the user issues view produced a little weird result (which obviously passed me by before). The cache key used in those queries are identical for ever Jira instance, so the cache will be filled with one of them, overwriting the other.

This PR fixes this by prepending the instance url to the cache key, so they become unique for every [user+instance].
