#authenticate_with_http_token raises an exception from 6.1.1 If token.blank?

[kentakag]

Steps to reproduce

1. Send http request with authorization header type, but without credentials

token = nil # or token = ''
request.headers['Authorization'] = "Bearer #{token}"
request.get

2. Use authenticate_with_http_token to check the token.

authenticate_with_http_token do |token, _options|
  # 
end

Expected behavior

return nil.
Under 6.1.1, it did.

Actual behavior

NoMethodError:
       undefined method `start_with?' for nil:NilClass

The cause is probably this commit

System configuration

Rails version:
6.1.1
