Username is case sensitive in card configuration

[stellarore]

Using the readme configuration example, if I have a user registered as “Foo” in home assistant, the redirect card won’t work.

type: 'custom:tab-redirect-card'
redirect:
 - user: 'foo'
   entity_id: 'input.binary.is_home'
   entity_state: 'on'
   redirect_to_tab_index: 1
