With commit fbe56f89f75a8979e0ba48001a822518df2c66fe, the function
org-get-tags incorrectly removes uninherited tags from the list of tags
it returns, *even if* they are local tags.

Expected behavior: org-get-tags should always return local tags,
regardless of whether they are excluded from inheritance. The variable
org-tags-exclude-from-inheritance should only apply to tags in parent
heading or to file tags.

Actual behavior: if a local tag is in org-tags-exclude-from-inheritance,
org-get-tags will not return it.

This causes problems with functions that call org-get-tags. For
instance, if org-fast-tag-selection-single-key is set,
org-set-tags-command delete all local tags that are in the list
org-tags-exclude-from-inheritance.

I've attached a patch that fixes the issue.

Best,

Matt
