[bug#51211] [PATCH] gnu: synapse: Downgrade to 1.29.0.

[Felix Gruber]

As discussed in [1] and [2], python-synapse 1.44.0 does not work with
our version of python-cryptography.

[1]: https://lists.gnu.org/archive/html/guix-patches/2021-10/msg00732.html
[2]: https://issues.guix.gnu.org/issue/48655

This reverts commit a6c30da4dc963e8a6282773fd1c2048d856a6cb4.

 gnu/packages/matrix.scm (synapse): Downgrade to 1.29.0.
