sky-action-button doesn't load font-awesome class before use in HTML

[blackbaud-joshlandi]

Expected behavior

this.fontSizeClass should be set before the template uses it and the icon should be styled appropriately.

Actual behavior

Possible race condition with .subscribe() where call to service doesn't fully resolve before template uses the fontSizeClass property.

Steps to reproduce

• Have SPA or site with multiple tabs
• Have a sky-action-button element with an icon
• Visit tab containing element
• Visit another tab
• Go back to tab containing sky-action-button
• Notice errors in console

Hey @blackbaud-joshlandi, did you want to try to write a pull request for this, or do you want me to grab it this week?
