Subject: [PATCH] Strip attributes whitespace in universal media_player
 (#54451)

When using whitespace in attributes the lookup of the state attribute fails because an entity with whitespace in its name cannot be found.

Works:
entity_id|state_attribute

Does not work:
entity_id | state_attribute

Fixes #53804
