(ios) Fix setting of target-device to handset in combination with plugins and resource files

[skocks]

Platforms affected

IOs

Motivation and Context

when:

• setting the target device <preference name="target-device" value="handset" />
• using (any) plugins
• Adding a resource file <resource-file src="GoogleService-Info.plist" />

then:
TARGETED_DEVICE_FAMILY is reset to the default value of "1,2" while adding the resource file after handling the target device.

Description

Instead of creating a new instance of the xcode project via new xcode.project([...]) use the wrapped xcode project via projectFile.parse([...]).
This will reuse the cached xcode project, which is created when adding the plugins, and therefore maintain the changes when setting the target device.
The cached xcode project will then also be used when adding the resource file.

Testing

• add plugins
• set target-device to handheld
• add a resource file

verify, that TARGETED_DEVICE_FAMILY = 1; is written to the project.pbxproj file.

That was a misunderstanding.
Since it reads "If this Pull Request resolves an issue, [...]" I checked it, because no issue is linked and therefore not referenced. - I can uncheck or delete the passage.
