fix: Fix receiving an old key exchange breaking decryption
...
This was mostly caused by Dart not copying values but referencing
them. AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA.
We know make some assumptions about received key exchanges, so this
needs some field testing.

fix: Hopefully fix all tests being flaky
...
It seems that the varint encoding function would not work for
some integers as input. This should in theory fix this issue. Since
the SPK IDs are randomly between 0 and 2**32 - 1, it makes sense that
the tests fail only sometimes.

fix: Restore the ratchets in case of an error
...
This means that if the ratchet fails to decrypt a message, from the
outside it will be as if that one message had never been received.
Thus, the ratchet can be used normally. This is to guard against
messages that are received again.

The X3DH spec says that salt (presumably the nonce) is supposed
to be [0, 0, ..., 0] with the length of the hash. I seem to have
skipped over that.
From Section 2.2:
"HKDF salt = A zero-filled byte sequence with length equal to the
hash output length."
