[PATCH} Do not throw error when parameter of :tangle is not a string

[Jacopo De Simoi]

Dear All,

 in the current master branch, if the parameter :tangle of a src block is not
a string, tangling fails by throwing  an error when calling `file-name-
directory'  This patch checks if the parameter is a string before calling
`file-name-directory'.

This makes construct such as :tangle (when condition-applies "filename") work
again (as they did a few versions ago…)

Thanks for your time
Best
 Jacopo
