Description of problem:redhat-support-tool: UnboundLocalError: local variable 'timer' referenced before assignment.


Version-Release number of selected component (if applicable): redhat-support-tool-0.9.9-3.el7


Steps to Reproduce:
1. For me to reproduce the issue, I had to bring down my networking.
2. Then run # redhat-support-tool addattachment -c 0XXXXXX -f -z /path/to/file


Actual results:
redhat_support_tool.helpers.launchhelper - ERROR - local variable 'timer' referenced before assignment
Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/redhat_support_tool/helpers/launchhelper.py", line 106, in run
    return cls.non_interactive_action()
  File "/usr/lib/python2.7/site-packages/redhat_support_tool/plugins/add_attachment.py", line 437, in non_interactive_action
    useFtp=self.use_ftp)
  File "/usr/lib/python2.7/site-packages/redhat_support_lib/infrastructure/brokers.py", line 612, in add
    amnt = FtpHelper.ftp_attachment(fileName, caseNumber, fileChunk)
  File "/usr/lib/python2.7/site-packages/redhat_support_lib/utils/ftphelper.py", line 135, in ftp_attachment
    timer.stop()
UnboundLocalError: local variable 'timer' referenced before assignment


Expected results: Upload the file to the dropbox.
