add short_version label to vm_app_version metric (#877)

vmalert: skip automatically added labels on alerts restore (#871) 
Label `alertgroup` was introduced in #611 and automatically added to generated
time series. By mistake, this new label wasn't correctly purged on restore event
and affected alert's ID uniqueness. This commit removes `alertgroup` label
in restore function.
