Ensure fixed_schedule field is populated

Browse Source 
The jobs framework contains two functions for loading jobs
(ts_bgw_job_get_scheduled and bgw_job_from_tupleinfo). However, the
ts_bgw_job_get_scheduled function did not properly populate the
fixed_schedule field, which caused some bugs in the calculation of the
next execution time for a job. This PR ensures the fixed_schedule field
is populated properly.
