Live issue 2 consecutive, identical verses (but with different translation lines)

[DeeTigIT]

Hello devs,

Consider a song with 4 verses: V1 - no trans V2 - no trans V3 - songlines identical to V2, with trans V4 - no trans

So, V2 and V3 are the consecutive verses with identical song lines, but different translation lines. No translation means here: just a space character on the translation line.

Projection reveals:

• first forward: V1 -> V2 -> V3 -> V4

  V1 is shown without trans: OK V2 is shown without trans: OK V3 is shown without trans: not OK (the no trans of V3 keeps hanging here?) V4 is shown without trans: OK

• then backwards: V4 -> V3 -> V2 -> V1

  V3 is shown with trans: OK now V2 is shown with trans: not OK (the trans of V3 keeps hanging here!) V1 is shown without trans: OK

Turning off a translation using a space character on a translation line (V1, V2 and V4 in the example) is a realy nice feature in Quelea I encountered recently. I don't know if it's undocumented, but please keep this great functionality. We actually have a number of such songs with translation only on a part of the song verses (second voice for women, for example).

This behaviour is also seen in the 2018.1 release, so it's not an 2019.0 B2 issue.

Thanks for this - definitely seems to be a reproducible issue. We'll take a look.
