Description

Consider the following steps:

1. Three masters are started with UUIDs A, B, and C.
2. A is shut down and its data deleted. A new master with UUID D is started on the same machine.

After this, visiting /masters on B or C should show A, B, and C as the registered masters, since they are the masters in B and C's quorum. D's /masters should just show D. However, right now we show B, C, D in all three /masters pages.
