Refresh conn dialog on reconnect, allow device NotFound[CPP-711]

[john-michaelburke]

• If a device is NotFound we allow the app to continue retrying until the connection dialog is opened.
• Just before every reconnect we refresh the connection dialog.

The combination of these two changes allows for a USB device to reconnect after the pipe has broken. Another situation when NotFound will pop up is when the user tries to open a file that does not exist; however, we never attempt to reconnect to a file so this won't proc.

@john-michaelburke
Tested out the build with trying to update piksi over rs232-usb adapter. This time, the console just disconnected after trying twice to keep the pipe open. And I couldn't re-open the pipe or see any FW update messages at all. We kind of walked backwards on this one as now, we don't see any FW update messages.
Hence, I am going to request changes on this merge :(

@RaiBearG I bumped up the timeout a little bit and it looks much better. I am seeing the message you expect come in. Here is a new tag with the changes:
