Test failures with numpy 1.9

[Tim Graham]

Installing numpy 1.9 and ./runtests template_tests will give some test failures like this:

Template test (Cached='True', TEMPLATE_STRING_IF_INVALID='', TEMPLATE_DEBUG=True): numpy-array-index02 -- FAILED. Got <type 'exceptions.IndexError'>, exception: index 5 is out of bounds for axis 0 with size 2
Traceback (most recent call last):

    value = self._resolve_lookup(context)

    current = current[bit]

IndexError: index 5 is out of bounds for axis 0 with size 2

[Tim Graham]

Here is the change in behavior:

NumPy < 1.9

>>> numpy.array(["first item", "second item"])['2']
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: field named 2 not found

NumPy 1.9+

>>> numpy.array(["first item", "second item"])['2']
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
IndexError: index 2 is out of bounds for axis 0 with size 2

Attaching a patch to fix it. I guess we shouldn't backport, but require specific version of test dependencies in Jenkins as suggested in #21793.

The original issue where these tests were added: [7d5e35cd].
