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

[lianbenjamin]

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.
