bfgd: drop btc_blocks_can refresh triggers for l2_keystones/pop_basis (…

…#120)

* do not refresh btc_blocks_can on l2_keystones insert/update

prior, we were refreshing a materialized view on each l2_keystones insert/update.  this isn't needed as the materialized view doesn't use that table.  so remove that trigger.

* drop trigger on pop_basis as well
