#14025: Flush command not fully supporting multi database support

Flush has not been reworked with multi database
Story:
If one use two different databases (ie, with different models in both)
flush emits the emit_post_sync_signal on EVERY model for EVERY database.
However since models may not be present (no django_site on legacy
databases for example) an exception is raised which in turn breaks tests.
I ran into this even if I had no fixtures or no database access:
{{{
ERROR: test_basic_addition (modulemanagement.tests.SimpleTest)
