tags: update tag type only if tag node is updated (issue3911)

Before this patch, tag type information is always updated, even if tag
previously read in has higher priority than one newly read in.

This causes that the tag type is displayed as "local", even if global
tag overwrites existing local one successfully.

This patch updates tag type only if tag node is updated.

This patch tests overwriting local tags below:

  - visible one (normal case)
  - already removed one (recorded as null)
