camera.snapshot 'no access to path!' error in 0.65.x

[mvdarend]

Make sure you are running the latest version of Home Assistant before reporting an issue.

You should only file an issue if you found a bug. Feature and enhancement requests should go in the Feature Requests section of our community forum:

Home Assistant release (hass --version):
0.65.2 and 0.65.3 0.64.3

Python release (python3 --version):

Component/platform:
Raspberry Pi 3

Description of problem:
camera.snapshot seems to have broken in the 0.65.x 0.64.3 release. I was running 0.64.2 and it worked fine untill I updated to 0.65.2, I then received the error 'Can’t write ‘/tmp/snapshot_front_door_1.jpg’, no access to path!'

Expected:
Expected it to write to the given path :)

Problem-relevant configuration.yaml entries and steps to reproduce:

whitelist_external_dirs: /tmp/

homeassistant user has full access to the /tmp/ folder

        entity_id: camera.front_door_camera
        filename: "/tmp/snapshot_front_door_1.jpg"

Additional info:
Reverting to version before 0.64.3 fixes the problem, it now works as before. I'm now running version 0.64.2 again and it works as expected.

Seem to be related to a fix in the 0.64.3 release:

@mvdarend as you mentioned in the forum, likely to #12810.

File paths and directory paths must be handled differently and will look into this for you

Found a workaround while it gets fixed: create a file with the same name of the snapshot in the same folder.
The camera.snapshot service won't throw an error and your file will be overwritten.
