Repositories Preflet breaks repositories

Double click on the listed repositories a few times, and the preflet breaks the system's repositories:

 pkgman update
Error: Failed to open repository file "/boot/system/cache/package-repositories/Haiku": No such file or directory
Refreshing repository "Haiku" failed: No such file or directory
Error: Failed to open repository file "/boot/system/cache/package-repositories/Haiku": No such file or directory

Error: Failed to open repository file "/boot/system/cache/package-repositories/HaikuPorts": No such file or directory

Further complicating things...

> pkgman add-repo https://eu.hpkg.haiku-os.org/haiku/master/x86_64/current
Fetching repository info from https://eu.hpkg.haiku-os.org/haiku/master/x86_64/current ...
Activating repository config from https://eu.hpkg.haiku-os.org/haiku/master/x86_64/current ...
A repository configuration for Haiku already exists.
overwrite? [yes/no] (no) : yes
Error: Failed to open repository file "/boot/system/cache/package-repositories/Haiku": No such file or directory
*** request for refreshing repository "Haiku" failed : No such file or directory

> pkgman drop-repo Haiku
Removing repository Haiku ...
Really remove the repository 'Haiku'? [yes/no] (no) : yes
Error: Failed to open repository file "/boot/system/cache/package-repositories/Haiku": No such file or directory

pkgman can't seem to recover from this situation.

actually, the drop-repo worked.. the error was non-fatal to the drop process.

This isn't the real issue.. It just triggers #15230
