sql: Implement Database::HasActiveTransactions().

HasActiveTransactions() is a replacement for transaction_nesting(),
which exposes too much detail, and references nested transactions, which
is a mis-feature.

This CL also updates Transaction's unit tests to more thoroughly cover
both HasActiveTransactions() and transaction_testing().

This CL does not introduce any functional changes. Follow-up CLs will
replace transaction_nesting() usage with HasActiveTransactions(), and
eventually remove transaction_nesting().
