The tmp name and perm name are the same. The tmp is just in .tmp

I am removing the '-'. This checks for alphanumerics only.

bq. Summary
bq. -------
bq.
bq. Adds a new test that fails w/o this fix and changes the naming scheme for
storefiles to use UUID instead of random longs as ascii.
bq.
bq. The big change is that the name of the tmp file used when flushing and
compacting is the same name (but different dir) when moved in place. This
makes it so block names are consistent for COW.
bq.
bq.
bq. This addresses bug HBASE-3417.
