Import-AzContainerRegistryImage returns bad request

### Description

Import-AzContainerRegistryImage returns bad request but running `az acr import` with a similar parameter set succeeds.

`Import-AzContainerRegistryImage -ResourceGroupName my-shared-rg -SourceRegistryUri mysharedcr.azurecr.io -SourceImage blogifier:latest -RegistryName mysharedcrtemp` fails

`az acr import --name mysharedcrtemp --source mysharedcr.azurecr.io/blogifier:latest --image blogifier:latest` succeeds

`Login-AzAccount` and `az login` both used the same account.

`Import-AzContainerRegistryImage` should successfully import the image if `az acr import` is able to.

The debug logs indicate an authentication error but `Resolve-AzError` says `Input string was not in a correct format.`. Where the parameter values for the PowerShell cmdlet are different to the az cli this is in accordance with the [docs](https://docs.microsoft.com/en-us/powershell/module/az.containerregistry/import-azcontainerregistryimage?view=azps-7.3.0).
