Cleanup: Use QString as parameter for [get|save]BtDeviceInfo()

Browse source 
Each callsite of saveBtDeviceInfo() has a QString, which is converted
to a C-string, passed and immediately converted back. Remove these
conversions by taking a reference to QString directly.

getBtDeviceInfo() is not as clear. Here, the callsite has a C-string
handed down from libdivecomputer. Nevertheless, pass a reference of
QString here as well. Firstly, for reasons of symmetry. Secondly,
to avoid multiple conversions in the getBtDeviceInfo() functions.
