userAssignedIdentities: type error on certain modules being deployed,

[jrspinella]

Describe the bug type error on certain modules being deployed,

change all modules that use this:

var identity = identityType != 'None' ? { type: identityType userAssignedIdentities: !empty(userAssignedIdentities) ? userAssignedIdentities : {} } : {}

to

var identity = identityType != 'None' ? { type: identityType userAssignedIdentities: !empty(userAssignedIdentities) ? userAssignedIdentities : null } : null

This should fix all the type errors.
