fix(FEC-11304): missing entryId on plugins (#453)

Issue: 
1. sources weren't taken for evaluation - 
`setSources` after configure: evaluator needs the config.source but it didn't update cause `setSources` called after.
`setSources` before `configure`: `sourceSelected` called but `entryId` didn't configure yet.
2. plugin doesn't load correctly from `setMedia` -
plugin config passes throw after sources loaded and then the plugin won't load.
Solution: 
Pass sources config to evaluation so plugin and sources will be loaded correctly.
