Useful for graphs with existing ontologies to avoid noisy
and needless exporting. Also update related scripts and noted
that create script has always been able to also update
instead of confusing :build/block. Also improved related tests,
simplified import steps, added some missing sqlite.build docs,
and fixed :build/uuid not working for some existing journals.
frontend.test.helper was accidentally coupled to sqlite3 via
logseq.outliner.db-pipeline. Split out sqlite3 dependent fns to
logseq.outliner.cli so it's clear this shouldn't be coupled to frontend
Converted inferred graph to an EDN file now that this task exists. Also
merge last of tasks.create-graph to relevant ns so that external users
can also create such tasks
