FCM/GCM: template parameters are not correctly replaced

[Krumelur]

I'm using the Notification Hub client lib 1.0.9

I am registering a template like this:

{
 "notification"  :  {
    "title"  : "$(sender)",
    "body" : "$(message)"
  } 
}

When I send my templates message I populate the params dictionary with the keys sender and message and they will be replaced as expected and result in the following output:

{com.google.firebase.messaging.RemoteMessage$Notification@305d335}
	Body: "hallo2"
	Title: "Bulk message from backend"

Notice how body and title are correctly set.

Then I change my template to include additional text like below:

{
 "notification"  :  {
    "title"  : "$(sender)",
    "body" : "Some other text. $(message)"
  } 
}
		

and the result is:

{com.google.firebase.messaging.RemoteMessage$Notification@4c9d296}
	Body: "Some other text. $(message)"
	Title: "Bulk message from backend"

The message placeholder is not being replaced anymore. This is for FCM/GCM only and work fine for iOS templates.
