Tweak the usage of the sqlite database to make common use cases
more responsive. In most cases copying the data to the sqlite
database takes so long that using sqlite doesn't have enough
advantages.
(TransientTableBase.ValueRange): Add
comments about performance and query the min and max in separate
statements because only that way will indexes be used.
(TransientTableBase.UniqueValues): Add some comments about
performance.
(AutoTransientTable.ValueRange, AutoTransientTable.UniqueValues):
Do not copy the data to the transient DB but use the transient
copy if it exists. See the new comments for the performance trade
offs
