Custom module versions are created twice currently

[dave-mills]

When an XlsformTemplate is made available, teams automatically receive an XlsformModule and XlsformModuleVersion for it. (For adding their own custom indicators). (\App\Models\XlsformTemplate - line 42). Here, the version is called "custom".

When an XlsformModule is created, it also creates a "Global" version for the module.

These are currently clashing and we are getting 2 different versions for each 'custom xlsform module'.

We should resolve this - probably by deferring to the default creation of XlsformModuleVersion entries. (or changing how custom modules are created to let teams have multiple custom modules per form if needed).
