4953: Uri Resolver: remove jumps of scope from Readers (for Generic and Runtime resource) 

Task-Url: https://support.d4science.org/issues/4953

All jumps has been removed
When is need to set scope in order to discovery a certain resource in a specific scope in the end the original scope is restored
