BugFix/Fix white space in USFM export

[PhotoNomad0]

Describe what your pull request addresses (Please include relevant issue numbers):

• fix for white space character after \p (\p should not have any trailing spaces before the newline #7164)
• fix for white space before first attribute in milestone markers (the pipe character | within the \w and \zalns has a space after it on export #7165)

Please include detailed Test instructions for your pull request:

• test with build below
• start with this project: https://git.door43.org/lrsallee/en_ult_1pe_book
• note percent complete on alignments (I see 99%) Fix the invalidated verse so it gets to 100%
• do export of Project to usfm and include alignment data
• open the USFM file in a text editor and should see as below. Mark sure there is no space after the \p token before a verse marker. Also check that \zaln-s and \w tokens do not have a space between the | and the first attribute.
