[7.0] Filtering tasks by Tags will also filter out all Tasks with no Tags asigned

[Michael Karrer]

If i create an advance search for Tasks to filter out all tasks with a specific tag (eg.: Support) it will also filter out all tasks with no tags set. Expected behavior would be to still show all tasks with no tag.

How to reproduce Case A:
---
1.) Create a least three Tasks: one with the tag "support" one with the tag "bugfix" and one with no tags at all
2.) Create an advanced filter for tasks with "Context" "doesn't contain" "bugfix"

Result: Only the Task with no tag assigned is gone Filtering out the Task with the Tag "bufix" did not work at all

Expected: The Task with the Tag support is gone an the task with no tag assigned is still there

How to reproduce Case B:
---
1.) Create a least three Tasks: one with the tag "support" one with the tag "bugfix" and one with no tags at all
2.) Create an advanced filter for tasks with "Context" "is not equal too" "bugfix"

Result: task with tag "bugfix" AND the the task with no tag is gone

Expected: Only the task with the tag bugfix should be filtered out

For sure you could try to combine two filters like "tag" "is not equal to" "bugfix" or "tag" "is not set" BUT this is very limiting since if you assign another tag to the task with the tag bugfix "is not equal to" will no longer work!
