### What?
Two things:
1. Users unassigned to a tenant could not access their own account
2. Custom `tenantsArrayFieldName` and `tenantsArrayTenantFieldName`
configurations were not being used in all cases
### Why?
1. The access constraint provided by the plugin would not allow them to
make changes to their own account
2. `getUserTenantIDs` and `afterTenantDelete` were not using the custom
field names properly
### How?
1. Adds constraint for users allowing them to manage their own account
by default. Externally nothing has changed. If you need to lock your
users access control down you should do that just as you would without
this plugin.
2. Threads the field names through for usage.
