search for ANY emoji-reaction
~"feature proposal"
## problem to solve
Currently we can only search for: `my-reaction:emoji`

But there are situations, where the user cannot specifiy the exact emoji.
Examples:
* User tries to find an issue he emoji-reacted, but doesn't remember the specific emoji type.
* User wants to list all issues he emoji-reacted, regardless of emoji type.
## feature suggestion:
:bulb: add ability to search not just for a specific emoji-reaction but for **any** emoji-reaction
## example:
instead of searching for `my-reaction:star`
search for: `my-reaction:any` (where any is a wildcard keyword)
