* Update cordova-plugin-meteor-webapp to version 1.7.0.
Fixes#10516.
* Bump meteor-tool and webapp to a temporary 1.8.1-issue-10516.0 version.
I attempted to publish webapp@1.7.4-rc.0 with @rj-david's changes from
https://github.com/meteor/cordova-plugin-meteor-webapp/pull/78 to verify
that they fix#10516, but prerelease versions like 1.7.4-rc.0 are not
compatible with non-prerelease core package constraints like ~1.7.3 (which
desugars to >=1.7.3 <1.8.0), as explained by this comment in the semver
source code: 5fb517b290/semver.js (L1246-L1250)
While this behavior was somewhat surprising to me, I haven't come up with
a way to fix it without accidentally allowing any prerelease version of
core Meteor packages to be installed in applications using an official
(non-prerelease) version of Meteor.
Instead, we can just cut a temporary prerelease version of Meteor itself.
If that fixes the problem, then we can publish webapp@1.7.4 safely,
without actually publishing a Meteor 1.8.1.1 release just for this.
* Update webapp to version 1.7.4 (without -issue-10516.0 suffix).
