Bug#830715: musescore: just rebuilding from source package fixes this

[Giacomo Mulas]

Package: musescore
Version: 2.0.2+dfsg-2
Followup-For: Bug #830715

Dear Maintainer,

musescore became uninstallable when qtquick1 was removed. 
However, it builds flawlessly from the source package: I just did it 
locally and obtained an installable and perfectly working musescore
package. Please just rebuild it ignoring (or removing) the 
build-depends: qtquick1-5-dev and you will get a working package.

Thanks, bye
Giacomo
