Fix lightproptime for cases when there is no SPEC TDC

[asanchezcastillo]

Description

When there is no SPECTDC products on the event the light propagation module does not put any sbn::CorrectedOpFlashTiming object on the event, which causes an error. This PR fixes the issue by replacing the return statement with a continue statement.

It does also fix a minor bug found when running pds-only reconstruction. Waveform alignment module was not correctly configured in this case.
