36952	Fix alter_field when called on a field that not has attribute: concrete	Junior Andrade		"Fix alter_field when called on a field that not has attribute: concrete

When alter_field on class BaseDatabaseSchemaEditor is called on a field that not has attribute concrete, a exception is raised:
AttributeError: 'BooleanField' object has no attribute 'concrete'

Should avoid this exception by checking if the field has the attribute."	Bug	closed	Database layer (models, ORM)	6.0	Normal	needsinfo			Unreviewed	0	0	0	0	0	0
