InstructionView not being rendered in LayoutPreview

Personne n'a encore pris cette issue.

**Android API:**
**Mapbox Navigation SDK version:** 1.0.0-rc7 of both normal and ui sdk.

### Steps to trigger behavior

1. Include `com.mapbox.navigation.ui.instruction.InstructionView` in a layout
2. Build project
3. Layout Preview fails to render layout, as somewhere something uses `ConnectionPool`, which shouldn't be done when `isInEditMode()`.

### Expected behavior
InstructionView preview renders with static/sample data, showing the customized colors

### Actual behavior
Class can not be instantiated and therefore can't be previewed.

Commencez par les constructeurs de InstructionView et l’initialisation de GuidanceViewImageProvider indiqués dans la stack trace, puis suivez l’endroit où ConnectionPool est créé pendant Layout Preview. Vérifiez le chemin isInEditMode et assurez-vous que Layout Preview restitue InstructionView avec des données statiques ou d’exemple et des couleurs personnalisées sans l’exception.
