Update Sync All Facilities Modal to allow unregistered facilities to sync

[LianaHarris360]

Observed behavior

When pressing Sync All to open Sync all facility data modal, the sync submission is disabled with the tooltip message 'There are no registered facilities on this device'. Because facilities could already be registered and may not know until they are synced, the sync button should not be disabled and the tooltip message should be removed..

The message 'You must be connected to the internet' is also incorrectly displayed.

Expected behavior

When Sync All button is pressed, the sync button should not be disabled on the opened modal. If user is connected to the internet, the message 'You must be connected to the internet' should not be displayed.

User-facing consequences

Users are unable to sync unregistered facilities when clicking Sync all.

Steps to reproduce

1. Navigate to Device > Facilities
2. Select Sync all
3. If facility is unregistered, the sync button is disabled and on hover, the message 'There are no registered facilities on this device' is displayed
