Update of VM tags is not working in v1.14.0

[ashbondu]

Tried the following operation
virtualMachine.update().withTag("test", "testValue").apply();
Results in the following request body in v1.14.0

{"properties":{"hardwareProfile":{"vmSize":"Standard_D4_v3"},"storageProfile":{"imageReference":{"publisher":"MicrosoftWindowsDesktop","offer":"Windows-10","sku":"RS3-Pro","version":"latest"},"osDisk":{"osType":"Windows","name":"OSDISKwin10","caching":"ReadWrite","createOption":"FromImage","managedDisk":{"id":"/subscriptions/subscriptionId/resourceGroups/resourceGroupName/providers/Microsoft.Compute/disks/OSDISKwin10"}},"dataDisks":[]},"osProfile":{"computerName":"win10","adminUsername":"vmware","windowsConfiguration":{"provisionVMAgent":true,"enableAutomaticUpdates":true},"secrets":[]},"networkProfile":{"networkInterfaces":[{"id":"/subscriptions/subscriptionId/resourceGroups/resourceGroupName/providers/Microsoft.Network/networkInterfaces/NICwin10","properties":{"primary":true}}]}}}

Tried the same operation in v1.10.0 which was working for us till now. The request body contains the new tag added.
{"properties":{"hardwareProfile":{"vmSize":"Standard_D4_v3"},"storageProfile":{"imageReference":{"publisher":"MicrosoftWindowsDesktop","offer":"Windows-10","sku":"RS3-Pro","version":"latest"},"osDisk":{"osType":"Windows","name":"OSDISKwin10","caching":"ReadWrite","createOption":"FromImage","managedDisk":{"id":"/subscriptions/subscriptionId/resourceGroups/resourceGroupName/providers/Microsoft.Compute/disks/OSDISKwin10"}},"dataDisks":[]},"osProfile":{"computerName":"win10","adminUsername":"vmware","windowsConfiguration":{"provisionVMAgent":true,"enableAutomaticUpdates":true},"secrets":[]},"networkProfile":{"networkInterfaces":[{"properties":{"primary":true},"id":"/subscriptions/subscriptionId/resourceGroups/resourceGroupName/providers/Microsoft.Network/networkInterfaces/NICwin10"}]}},"location":"westus2","tags":{"test":"testValue"}}

Clearly the new tags added are missing in the @patch request created in v1.14.0.
Hence the Azure is not adding the new tags to the VM resource.
