Route page: Show foto's tab when no summit book

[erikvanoosten]

On the route page, when there is no summit book, please activate the foto's tab by default. I never add a summit book (to be honest, I don't even know what it is), but I do try to always add foto's.

Here is an example page where this would be beneficial: https://--wanderer--.grons.nl/trail/view/@erik@wanderer.grons.nl/90b00cfe4600259 (remove the dashes in the host name).
