Description

Hi,

We recently upgraded from v0.24.6 to v1.0.0 using the deb package and encountered this issue:

error.4024 The filter expression '{"filter":"done = 'false"}'' is invalid: unexpected character '{'

https://community.vikunja.io/t/problems-loading-list-tab-in-projects-filter-error/4060.

I don't really understand why this happened, as we only had those two versions on our server and this issue was not present on our test server where we tested the upgrade.
Even stranger, not all projects had this incorrect filter configuration ({ "filter": "done = false" } instead of done = false) in their list view, despite all projects being created in v0.24.6.

I have already run 'vikunja migrate', but this did not fix the issue.

Thanks in advance.

Markus
