Retrieve number of wells and completions at the beginning of the
simulated step. Otherwise a well introduced at the same time step as the
report will be included - even though there doesn't exist any simulated
data yet.
This issue would trigger a throw if WRFTPLT was added at the same time
step as a well is introduced in the schedule section.
Removed one DATES item in FIRST_SIM.DATA. The
EclipseReadWriteWellStateData in test_Restart compared state at T1,
which did not include any well data as it was. No other tests were
affected.
