handles restoration for each platform separately so that if one fails installation for
others continues. Also makes a change on how the host is checked to allow such errors
not to completely halt the execution.

CB-7311 Fix xcode project manipulation on Windows host

When adding plugins on Windows, plugman will insert incorrect paths,
which also contain backslashes into the xcode project files. This breaks
builds of the iOS app in Xcode and requires manual editing of the
project file.

On all non-Windows platforms, where the path separator is already `/`,
the performed replace should be a noop, on Windows it fixes the paths in
the project file.

Fix: scriptsFinder crashes if event based hook removes a plugin

getAllPluginsHookScriptFiles was using the list of plugins from opts.plugins
which becomes outdated if an events based hook removes a plugin. The function
was failing while trying to create PluginInfo('dir/of/deleted.plugin') with:

Error: Could not find plugin info in .../tstApp/plugins/org.apache.cordova.engine.crosswalk
