property: create property names more eagerly.

Browse Source 
User defined property names were not created before the first fetch.  The
rationale for this was to only maintain the user names defined by providers.
This was intended to prevent malicious memory use attacks.

Not being able to specify a default query before the first fetch is wrong.  This
changes the behaviour of the property query parsing to always create property
names.

Fixes #15218
