Retrieve assigned resources from PractionerDetails contained field

[Rkareko]

Describe the feature request.
The current implementation stores the user assignment resources in the FhirPractitionerDetails class.
During parsing of the bundle on the android app the HAPI FHIR JsonParser only populates 1 item for each of the fields in the FhirPractitionerDetails even though the payload from the server contains multiple values. This issue is documented #3659

The HAPI FHIR JsonParser parses all resource entries in the contained field correctly.

As such, changes have been made on the server that populate the PractitionerDetails.contained field with the user assigned resources such as locations, teams, groups e.t.c

The LoginViewModel.savePractitionerDetails needs to be updated so that the assigned resources are retrieved from the PractitionerDetails.contained field
