Update HasTags() and HasPaths() to follow #1081 idea

Browse Source 
Replace all but 3 occurences of StringSliceVar to StringArrayVar. This will
prevent the flag parser to interpretate the given values as CSV string.

Both --tag, --keep-tag and --path can be given multiple times, the command will
match snapshots matching ANY of the tags/paths. Only when a value is given which
contains a comma separated list of tags/paths, ALL elements need to match.
