Bug 13706

Occurs in build 010717_1. It worked in EA build.

Suppose you have normal filesystem (not webmodule) mounted. 
1. Create servlet from template
2. Cut it and paste it to other directory.
Exception is thrown and package isn't changed in source so message "invalid
package declaration" appears in tooltip of servlet node.
