fixed a rare case where assets urls are created invalid

[vannidellaricca]

Hi,
we found an rare case in which library return an invalid url.
some preconditions:

• php engine jail in chrooted mode ( or DocumentRoot is in root filesystem).
• base root have the same name of domain
  which this condition in file Config.php on method get_url the function str_replace trigger the transformation many time for the string.
  this is te our test env

wp_list_pluck( $bases, 'base_dir' ) return

Array
(
    [wpmu_plugin] => /miodominiouno.it/ita/wp-content/mu-plugins
    [wp_plugin] => /miodominiouno.it/ita/wp-content/plugins
    [wp_content] => /miodominiouno.it/ita/wp-content
    [plugins] => /miodominiouno.it/ita/wp-content/plugins
    [stylesheet] => /miodominiouno.it/ita/wp-content/themes/twentytwentyfive
))

wp_list_pluck( $bases, 'base_url' ) return

Array
(
    [wpmu_plugin] => http://miodominiouno.it/ita/wp-content/mu-plugins
    [wp_plugin] => http://miodominiouno.it/ita/wp-content/plugins
    [wp_content] => http://miodominiouno.it/ita/wp-content
    [plugins] => http://miodominiouno.it/ita/wp-content/plugins
    [stylesheet] => http://miodominiouno.it/ita/wp-content/themes/twentytwentyfive
)

the transformation return
http:/http:/http://miodominiouno.it/ita/wp-content/plugins/the-events-calendar/common/

we have made a test using strtr that perform only one substitution and the code works.

We attach a 1 line patch

@vannidellaricca thank you for this PR.

I would love to see us have a Test set for this @dpanta94 before we merge.

Not 100% a priority but worth the time after we finish Tyson.

Hi,
any time for this task.. we need to patch manually the events calendar and event ticket at every update.
Do you prefer that an issue be opened for you?
