[evolution-ews] Use G_IO_ERROR_CANCELLED instead of EWS_CONNECTION_ERROR_CANCELLED

[Milan Crha <mcrha src gnome org>]

commit 2f41029324d0d0e68caa2cbc911e982b48440f5e
Author: Milan Crha <mcrha redhat com>

    Use G_IO_ERROR_CANCELLED instead of EWS_CONNECTION_ERROR_CANCELLED
    
    The first is checked for on many places in the UI, while the later
    is not checked anywhere. The outcome was that a cancelled operation
    added a warning in the UI about "Operation Cancelled", which is
    useless.
