[TIMOB-27757] watchOS: Frameworks are referenced incorrectly

When including native watchOS frameworks (and the build doesn't fail because of TIMOB-27756), the build later fails because the source files cannot find the frameworks. After some research, I found out that the frameworks are linked incorrectly, although linked correctly in the source project. It seems like a simple path issue somewhere, but it nukes the frameworks and marks them with a white icon (showing that they cannot be found). The issue can be reproduced in our app. *EDIT*: I found the reason:

Current pbxproj line (invalid):

		3A870A3023F1EE1600E07E86 /* MyFramework.framework */ = {isa = PBXFileReference; lastKnownFileType = wrapper.framework; path = MyFramework.framework; sourceTree = "<group>"; };

should be:

		3A39B9AF23F2AE7800FF2AC3 /* MyFramework.framework */ = {isa = PBXFileReference; lastKnownFileType = wrapper.framework; name = MyFramework.framework; path = extensions/my_watch_app/MyFramework.framework; sourceTree = "<group>"; };

The pbxproj entry is missing the „name“ and „path“. Also, there is a missing framework search path $(PROJECT_DIR)/extensions/my_watch_app which should be added when the other refs are written. The issue behind it is that frameworks are stored at different subdirectories when copied from /extensions/xxxx to /build/iphone/extensions/xxxx but the path is not updated. A workaround is to hardcode the following hacky code below [these lines](https://github.com/appcelerator/titanium_mobile/blob/master/iphone/cli/commands/_build.js#L3411):

const currentFileRef = Object.assign({}, xobjs.PBXFileReference[extFrameworkReference]);

if (!currentFileRef.path.includes('extensions/') && currentFileRef.sourceTree === '"<group>"') {
    xobjs.PBXFileReference[extFrameworkReference].path = extensions/MyExtensionName/${currentFileRef.path};
    xobjs.PBXFileReference[extFrameworkReference].name = currentFileRef.path;
}
