animallocation table is still being created with column named "By"

[traviswparker]

dbupdate.py update_34803 is creating table animallocation using the reserved MySQL keyword By for a column name. A later update function renames the column to MovedBy

This breaks updates from 47 on MySQL as the table is never created. Modifying update_34803 to create the column as MovedBy and rolling back the DBV config value to 34802 allows the schema update to proceed.

Should probably create the column as MovedBy and allow the later rename to fail if it is already MovedBy

Thanks for the feedback, updated now.
