update glyph placement to verify all glyphs are valid

[ragnarok56]

Resolves #1224

Addresses an issue with glyphs where first/last glyphs are assumed to be sufficient to place all remaining glyphs using placeGlyphAlongLine which can return a null value and throws an exception later in placeGlyphsAlongLine.

Thanks for taking the time to solve this!
It would be great if you could create a test for this.
Hopefully a render test to showcase the issue and the solution.
Let me know if you need help with wiring the test.

Trying to come up with a render test that can recreate it, but having some issues identifying the exact scenario that causes it to fail. I don't have access to the environment this is was occurring in right now. I'm also not certain if it 100% happens on just rendering or if it was being triggered from zooming in/out of the area and maybe that is part of the calculus involved, if so then a render test may not be sufficient by itself?

Also not at all familiar with how placeGlyphAlongLine works and how to trigger the error case where one of the symbols fails to be placed along a line after the first/last check is done.

If you can't create a test to reproduce it, it will be impossible in the future to make sure this won't break again...
Also it will make testing that this actually fixes the issue harder...
