[Why] It can return an error. (cherry picked from commit 913bd9f)
[Why] The code assumed that the transaction would always succeed. It was kind of the case with Mnesia because it would throw an exception if it failed. Khepri returns an error instead. The code has to handle it. In particular, we see timeouts in CI and before this patch, they caused a crash because the list comprehension was asked to work on a tuple. [How] We now retry a few times for 10 seconds. (cherry picked from commit 4621fe7)
