Make !grids list create temporary gps instead of permanent

[sisko91]

Usually players use this command when trying to find a grid, and have to delete everything else they dont care about.

This is a one line change by adding an extra "true" at the end of this call https://github.com/TorchAPI/Essentials/blob/b19b8d9441915c90d2dff978b636d6aaea62dddc/Essentials/Commands/GridModule.cs#L175

This call has an optional param that defaults to false, which creates a permanent gps: https://github.com/KeenSoftwareHouse/SpaceEngineers/blob/a109106fc0ded66bdd5da70e099646203c56550f/Sources/VRage.Game/ModAPI/IMyGpsCollection.cs#L31
