Completion issue in visual studio

Enter vs tab has different behavior in visual studio. Enter retains the typed in text.
Steps to reproduce the issue:
1. Type vnet
2. Select res-vpn-vnet-connection from completion list

Expected:
```
resource vpnVnetConnection 'Microsoft.Network/connections@2020-11-01' = {
name: 'name'
location: location
properties: {
virtualNetworkGateway1: {
id: 'virtualNetworkGateways.id'
properties:{}
}
localNetworkGateway2: {
id: 'localNetworkGateways.id'
properties:{}
}
connectionType: 'IPsec'
routingWeight: 0
sharedKey: 'sharedkey'
}
}
```

Actual:
```
vnetresource vpnVnetConnection 'Microsoft.Network/connections@2020-11-01' = {
name: 'name'
location: location
properties: {
virtualNetworkGateway1: {
id: 'virtualNetworkGateways.id'
properties:{}
}
localNetworkGateway2: {
id: 'localNetworkGateways.id'
properties:{}
}
connectionType: 'IPsec'
routingWeight: 0
sharedKey: 'sharedkey'
}
}
```
