Removed deprecated method l from code base

Thanks for the effort. I'm getting several errors from the patch.

Example:

The website encountered an unexpected error. Please try again later.
Recoverable fatal error: Object of class Drupal\Core\Link could not be converted to string in _photos_order_link() (line 2343 of modules\photos\photos.module).

Also need to include:
use Drupal\Core\Link;

This is still breaking the module. Please test the module before submitting a new patch.

Recoverable fatal error: Object of class Drupal\Core\Link could not be converted to string in _photos_order_link() (line 2345 of modules\photos\photos.module).

how to solve this error ?
