Changing a column on sqlite from integer to varchar removes data types on unsigned integer columns

[josephmancuso]

Describe the bug
I believe this only happens Changing a column on sqlite from integer to varchar removes data types on unsigned integer columns

To Reproduce
Steps to reproduce the behavior:

1. create a migration that adds integer unsigned and assign it a foreign key to other tables

with self.schema.create("course_progress") as table:
            table.big_increments("id")
            table.integer("user_id").unsigned()
            table.integer("course_id").unsigned()
            table.integer("step")
            table.foreign("user_id").references("id").on("users")
            table.foreign("course_id").references("id").on("courses")
            table.timestamps()

3. then create another migration that changes the step column from integer to varchar

with self.schema.table("course_progress") as table:
            table.string("step").change()

now both the user_id and course_id columns lose their data types

Expected behavior
table should be fully rebuilt to include foreign keys and other columns
