"ERROR: query string argument of EXECUTE is null" when the table is empty

[useher]

If i try to initialize the versioning on an empty table the following error occurs:

`
select * from versions.pgvsinit('ne_1808.testtable');

ERROR: query string argument of EXECUTE is null
CONTEXT: PL/pgSQL function versions.pgvsinit(character varying) line 147 at EXECUTE
SQL state: 22004`

When i create content in QGIS, the initialization work as expected.
Question: Is this the intended behavior? For me, it would make more sense when a table can be versioned before content is put in, but i may be wrong with this. If this is intended, maybe a more readable message would be useful, especialliy in the QGIS-Plugin, which is often used by people with no database-knowledge.

It is not possible to set an empty table to the versioned state. In version 3.10.0 of the plugin a better error message is now displayed when trying to version an empty table.
