Button image is not centered

[CoffeePerry]

Description

I found a problem in Button's image centering when Application.MainPage property is set to a NavigationPage: image will be positioned on the left in the button, instead of in the center.

In App.xaml.cs, using:
MainPage = new NavigationPage(new HomePage());

Instead of:
MainPage = new HomePage();

In HomePage's buttons, images will be on the left instead of the center.

P.S.: I found this problem only in Android.

Steps to Reproduce

1. In App.xaml.cs, use:
   MainPage = new NavigationPage(new HomePage());

Expected Behavior

In HomePage, buttons images are on the center.

Actual Behavior

In HomePage, buttons images are on the left.

@mattleibow I guess we didn't fix 'em all 😆 (referring to #4967)

Is a fix expected to be applied soon? My image verification tests have failed because of this issue. 😄

A way to get around this problem is using ImageButton intead of Buttton, for now.

@CoffeePerry Thanks for the workaround. I have tested it and it works. For now I will use it. Still, I hope as the issue was introduced with one of the latest official releases to be addressed and fixed soon. Thanks again.
