Overwriting the hosts file #1
Description
If the user tries to unblock a website a FileNotFoundException will be thrown.
This Exception is thrown in the method saveIntoHosts that is called from the BlockedAndUnblockController.
The problem occurs when we try to set the append parameter of the FileWriter constructor to false, if append is set to true the method will not throw a Exception but the bytes will be written to the end of the file, but that is not the wanted result. The wanted result is to overwrite the whole file, this is possible only if append is set to false.
