Xpaths that match text need sanitised string substitution

[amyworrall]

This Xpath is used to get the value for the chosen option for reproducible status:

//select[@id='reproducibleNewProb'][1]/option[text()='%@']/@value

However, it fails when the status is I Didn't Try, since there's an apostrophe in it. All strings passed into Xpaths need proper escaping.

Fixed by replacing single quotes with double in the xpath. This is fine since we know all the values that might be substituted.
