simplewallet: warn about correlations if print-ring-members is not set

Browse Source 
The warning about spending more than one output with similar creation
time was skipped if print-ring-members was not set, and it defaults to
false, which means most people probably aren't getting this warning if
they spend correlated outputs.

Reported by SeventhAlpaca.
