Don't retry VCS detection for performance purposes

Browse Source 
For each new buffer sy#repo#detect() gets run. That function invokes callbacks
for all VCS from g:signify_vcs_list.

If no callback finds a valid repo, sy#set_signs() is never called and the VCS
type of the newly registered buffer keeps its initial value: "unknown".

The next time Sy gets run in that buffer, Sy will disable itself, so that all
subsequent times it gets run it will never even attempt to get a diff.

If a buffer was added to a repo that was initialized after Sy registered that
buffer, it will remain inactive.

In those cases, :SignifyEnable will purge the cache for the current buffer and
start all over.
