Cannot tab-complete warp names if the warp has a defined warp group

[HFogno]

If a created warp does not have a defined group (defaulted to N/A), you are able to tab-complete the name as normal when using /warp.

However, if you add the warp to a group, you are no longer able to tab-complete the name and have to type it out in full. It does still teleport you though.
