Major deserialization issue in release/20.12 git branch

[Daniel Vrátil]

Hi,

do you have the corresponding version of akonadi-calendar as well?

20.12 only has the compression disabled, but all the code is still there and 
will decompress that data if it detects they are compressed (even if 
compression is disabled), exactly to cover the case of those who used 
development versions of Akonadi where the feature was enabled by default for a 
while.

There was a bug in the calendar akonadi serializer plugin that I fixed and I 
just double-checked that it's in the 20.12 branch.
