Fix SimplifySearchVectorExpressionCommand (#8218)

## Context
This command was introduced to simplify searchVector expressions that
were added in v0.31.x for existing workspaces.
New search vector columns have been added later during 0.32 development
and should not be migrated, this actually breaks the command because we
run sync-metadata before the upgrade command.

The fix removes the throw since this is expected and return early if the
search vector was not matched with an object that needs migration.

## Test
checkout v0.31.0
reset:db command
checkout this PR
run typeorm migrations
run upgrade 0-32 command
