TextType - Over-length value validates when both max and min specified

[gsteinert]

Expected behavior

When both max and min are specified in a field definition, over length strings should be refused.

Actual/Current behavior

Over length string accepted

Steps to reproduce the actual/current behavior

Define a field as per below:
name: { type: Types.Text, required: true, min: 3, max: 5 },
Enter a string longer than 5 characters
Submit

Environment

Keystone master (0ca9eb1)
Node v9.2.0

Notes

Issue seems to be caused by a922b38. If min length validation passes, all other validation results are discarded.
