noise fails to build with newest vala + glib

The latest betas of some GNOME libraries (glib2, vala, etc.) break the noise build. The following error occurs during build:

> /builddir/build/BUILD/noise-0.4.0.2/core/Utils/TimeUtils.vala:51.74-51.80: error: Argument 1: Cannot convert from `uint' to `int'
> return ngettext ("%d second", "%d seconds", seconds).printf (seconds);
> ^^^^^^^
> make[2]: *** [core/CMakeFiles/noise-core.dir/build.make:210: core/noise-core_valac.stamp] Error 1

The relevant version changes are (I think):

vala 0.34.4-1.fc26 > 0.35.3-1.fc26
glib2 2.51.0-2.fc26 > 2.51.1-1.fc26

A list of all build dependencies that changed between the last good and the first broken build can be found at: https://apps.fedoraproject.org/koschei/build/2578272

This breakage might indicate a future problem for noise on elementaryOS loki+1(?), too, depending on which version of GNOME libraries make it into ubuntu in time (...)
