Peer Beckmann bb7787d2ee Remove the eager check in the browse middleware (#1144)
* Remove the eager check in the browse middleware, whether the root directory exists.
Caddy will start and throw a 404-error until the directory will be created.

* Add the complimentary test.
 - Tests the startup of the browse middleware if the site root is inexistent and browse is pointing to the site root.

* Some minor stylistic tweaks.
