restream stop if stop called, temp solution (#1092)

* restream stop if stop called, temp solution until new command for it

* chekckrestream is ambiguous when only checking receiver

* moved restreaming in background to receiver stop instead of detector stop (was in stop before due to gui stop button access), increase to 2s time to restream in client acquire

* minor

* moved stop to module class

* fix from before
