fix(FEC-14093): rapt is not loading on latest player (#834)

### Description of the Changes

**bugfix - regression**

**Issue:**
since the latest player changes, while loading rapt media, the player is
not being displayed on the page (blank space).
- as part of the latest changes in bottom-bar comp, we register a new
service in the constructor, which uses the `serviceProvider` member of
kaltura player
- rapt renders the bottom-bar component before kaltura-player finished
initializing - `serviceProvider` is `undefined`, which causes a runtime
error

**Fix:**
move `serviceProvider` initialization before initializing the ui.
