When a column was renamed in the Edit Table dialog, the column names
referenced in column and table CHECK constraint expressions were not
updated. SQLite itself rewrites them during ALTER TABLE RENAME COLUMN,
but the dialog's table definition still contained the old name, so
alterTable() saw a difference and recreated the table with a CHECK
referring to the old, no longer existing column.

Table::renameKeyInAllConstraints() now also rewrites the column name in
all CHECK expressions, leaving string literals, comments and function
names alone.
