Need to deal with collisions when renaming and merging namespaces

[amvanbaren]

Fixes #716
Merge namespace members
Return error if namespaces contain duplicate extensions

[kineticsquid]

@amvanbaren
Testing:

• renamed namespace to one that exists w/out merge
  • Correctly failed
• renamed namespace to one that exists w merge and duplicate extension
  • Correctly failed
• renamed namespace to one that exists w same member in same role in both
  • Correctly resulted in member listed once
• added myself (kineticsquid) as an owner to sasjs along with amvanbaren. Then attempted to merge namespace sasjs into kineticsquid (in which kineticsquid is only a member).
  • This test appeared to fail; both namespaces exist as they had prior to my rename/merge request. The rename/merge request appeared to have no effect.

On perhaps import ant detail: after submitting the final test, I got distracted on another topic before coming back to this task. I then could not remember if I'd actually submitted the namespace rename request (since after the pop up message you're left on the same page). So I submitted the request again. Not sure if this duplicate request caused any problems. Could you check the logs?

@amvanbaren Follow up comment. I made the above comment about 20 min after I did the final test (given the pop up message). On a whim I went back about an hour later and noticed that the test had completed successfully. It could have taken anywhere from about 25 min to 60 min to complete. Is that expected? Should we update the information in the popup message?

You mean this test?

Yes, the popup says: "15 minutes to a couple hours"

Doh... should have read that more thoroughly. Thanks! We're good.
