Fix #10443 - Incorrect lengths in emails_text vardefs

[ojs87]

Description

The fromaddr and reply_to_addr fields in emails_text vardefs are set to 250 when they should be 255. This has caused an issue where repair and rebuild keeps trying to recreate the index on the fromaddr field in some situations. https://github.com/salesagility/SuiteCRM/issues/10443
