port bump doesn't update all checksums in saxon

[pwidene (Patrick Widener)]

Edited version in saxon portfile to the latest version (9.5.1.10). port bump output indicates that both checksums in the portfile were updated, but debug output indicates only one patch was applied and inspection of portfile afterward confirms one old checksum remained.

Manually updating the remaining checksum then allowed me to install saxon as expected.
