Importing vlan resource without a name crashes terraform

[chanster]

Importing a ibm_network_vlan that does not have a name set fails.

Example of ibmcloud sl vlan list

ID        number   name           firewall   network_space   primary_router   hardware   virtual_servers   public_ips
2567033   3224     my-vlan1       No         PRIVATE         [REMOVED]        0          2                 61
2737798   3238     -              No         PRIVATE         [REMOVED]        0          4                 61

Expected Behavior

Import of ibm_network_vlan should complete

Actual Behavior

Import fails with crash error.

Steps to Reproduce

Please list the steps required to reproduce the issue, for example:

1. Create a IBM Cloud Classic Infrastructure VLAN without a name.
2. Create data source in Terraform config
3. Create resource in Terraform config
4. run terraform import ibm_network_vlan.[resource] [vlan_id]

Important Factoids

These VLANs were created manually through the IBM Cloud web interface.

Work around is to add a name to the VLAN after it has been created.
