EKF: Fix bug in initialisation of height and magnetic field
...
This prevents zero data being used to form the initial height and magnetic field.
Do not start sampling initial values until non-zero time values are retrieved from the buffer.

EKF: Fix scaling error in covariance prediction derivation
...
The covariance prediction derivation was using the noise 1-std value instead of the noise variance. This resulted in the values of IMU process noise required to tune not matching the observed covariance growth.
