[ui] sorting by # in all group leads to internal server error

[c-jaenicke]

Describe the bug Sorting by #/date_created in the all group leads to internal error. Sorting by #/date_created in any other group works, but after doing that and going back to all it breaks.

Clearing the cache resets the sorting and fixes the problem until you sort by #/date_created again.

Version v0.45.1

To Reproduce

Steps to reproduce the behavior:

1. Open overview page / all group
2. Click on # to sort by date_created
3. See error Internal Server Error

2nd way:

1. Open any group
2. Click on # to sort by date_created
3. Go to all group
4. See error Internal Server Error

Expected behavior Should load the all group sorted by date.

thanks for the report!

[dgtlmoon]

looks like update 11 didnt run correctly - https://github.com/dgtlmoon/changedetection.io/commit/0aa2276afbbe336148226338c68a237090b73787

fixed as a new update

[c-jaenicke]

Just tested locally, can confirm sorting works now.

Thank you

This one should only affect people who have watches since before the "update 11"
