Incorrect error message shown for import error

[megankatsumi]

Hello, It appears that WebProtege returns an incorrect error message when I attempt to load an ontology with an import that fails.

To reproduce:

1. create an empty test ontology
2. add an import statement for an ontology that doesn't exist (e.g. <Import>http://example.com</Import> )
3. attempt to load ontology as a new project in WebProtege

This results in the following message:

Please refresh your browser WebProtege has been updated. Please empty your browser caches and reload your browser.

Whereas I would expect a message indicating an import error (or even no message at all, and simply the generation of the project without including the ontology that failed to import).
