sig_new_file error when converting notebook to script

[StevenMMortimer]

Description

What steps will reproduce the problem?

1. Right-Click on an .ipynb file > Click on "Convert To Python Script"

What is the expected output? What do you see instead?

I expected to see a .py file generated based on the notebook, but instead received the following error in the internal console:

Traceback (most recent call last):
  File "C:\Program Files\Anaconda2\lib\site-packages\spyder\widgets\explorer.py", line 568, in convert_notebooks
    self.convert_notebook(fname)
  File "C:\Program Files\Anaconda2\lib\site-packages\spyder\widgets\explorer.py", line 559, in convert_notebook
    self.parent_widget.sig_new_file.emit(script)
AttributeError: 'Projects' object has no attribute 'sig_new_file'

@andfoy, this is a simple one for you :-)

@ccordoba12 I tried to reproduce the error, but the conversion worked successfully, I don't know if the error is related to Qt 5.x

@andfoy, did you do the conversion from the Project explorer instead of the File Explorer?
