Tags of loaded module should not apply to module with same name in different modulepath #599

Module tags applying to a loaded module also apply to module with same name but located in different modulepath.

$ module avail -t
/path/to/modulefiles.1:
foo/1

/path/to/modulefiles.2:
foo/1
$ module avail -t
/path/to/modulefiles.1:
foo/1 <L>

/path/to/modulefiles.2:
foo/1 <L>
$ echo $_LMFILES_ 
/path/to/modulefiles.1/foo/1

It is expected that these tags only apply to the loaded module and not to others having the same module name. In the provided example foo/1 from /path/to/modulefiles.2 should not be marked loaded.
