REGRESSION: code-review-tests.html fails with error "Received an error at line 214"

Reviewed by Darin Adler.

Fixes an issue where opening the file code-review-test.html in Safari shows the error message
"FAIL: Received an error at line 214" and in the console there is a JavaScript TypeError:
    undefined is not an object (evaluating '$('.overallComments textarea').val().trim')

Notice that test testReaddDiscardedCommentWithPreviousComment() is the only test that appends
the toolbar, which inserts the overall comments textarea. The test testSaveCommentsWithMissingLineIds()
assumes that the own properties of the window object are enumerated in the same order as they
were defined in the file code-review-test.html such that the test testReaddDiscardedCommentWithPreviousComment()
is executed before test testSaveCommentsWithMissingLineIds(). The behavior of JavaScriptCore with
respect to the enumeration order of properties on the window object have changed since the
test testSaveCommentsWithMissingLineIds() was written such that the order of the own properties
on the window object do not reflect the order in which they were defined in the file. We should
append the toolbar before running the tests and explicitly execute the tests in chosen order so
as to be able to reason of the test results regardless of the enumeration ordering of the
properties in the DOM window object.

Also, removed duplicate 'd' in the name of function "testReaddDiscardedCommentWithPreviousComment"
such that it reads "testReadDiscardedCommentWithPreviousComment".
