[BUGFIX] CsvUtility method csvToArray does not handle enclosures right

When we have a csv string with enclosures, the string is sometimes not
correctly transformed into a multidimensional array. The cause of this
is the first str_getcsv() function, responsible for exploding the rows.
It returns rows where the first column does not have an enclosure
anymore.

This patch fixes this by using fgetcsv(). A temporary file is created
and written to the typo3temp folder and then passed to fgetcsv(). This
way we get a correct multidimensional array from the csv string.
