Removed unnecessary quote escaping in issue.getIssueTitle()

This can be demonstrated with https://drupal.org/node/2075499. We should not escape any characters until we know what *should* be escaped, like when using it in a commit message.

The example provided has an issue title of:
`Is it possible to put a multiple-select exposed filter on a single date field with "Year" granularity?`

The commit message created is:
`git commit -m "Issue #2075499 by Offlein: Is it possible to put a multiple-select exposed filter on a single date field with 'Year" granularity?."`

Note the current code doesn't even correctly convert both double quotes, and the last PR fixes escaping the double quotes.
