Go to end of source block before org-table-align

This is necessary because otherwise blocks like this:
x
| x

Will turn into
x
| x

x
| x |

Since org-table-align will get called on | x, and turn it into | x |

I'm noticing this problem because of the automatic black formatting,
which frequently puts |'s at the start of lines.
