[Therion] Splays appearing when not selected

[Rhys Tyers]

Hello,

I have noticed something that I am not sure if it's a bug or not. I am
trying to export a selected bit of a survey as a loch file:

source "data/system_migovec.th"
select vrtnarija_vilinska at system_migovec
export model -o outputs/vrtnarija.lox

This seems to correctly export the centerline only for "vrtnarija_vilinska"
but if I turn on the walls in loch then other bits of the survey are shown.

Centerline correct:

With walls there are other bits of passage shown:

These seem to correspond to bits of passage that have splays and LRUD data
so it seems like those aren't correctly filtered out using the "select".

Using:
therion 5.5.6 (2020-12-27)
  - using Proj 6.3.1, compiled against 6.3.1

Thanks,
Rhys
