Stack empty error with incorrect or missing verse numbers

[pmachapman]

GetRows fails with the following error:

Message: 
System.InvalidOperationException : An error occurred while parsing the text 'MAT'. Verse: MAT 1:१, line: 6, character: 1, error: 'Stack empty.'

Given USFM with non-latin numbers:

\id MAT - Test
\c 1
\p
\v १
\p

Or when the \v tag is empty:

\id MAT - Test
\c 1
\p
\v
\b

What should probably happen is either the verse is ignored, or an error about the verse number being incorrect is thrown so that it can be corrected in the USFM.

Let's ignore this issue and keep going. Hopefully, the versification checks will add a warning for this issue.
