Fixed nested type resolution

[till0xff]

Fixed nested type resolution in an extension with a global type name in the same module.

Example

File Moya.xcframework/ios-arm64_x86_64-simulator/Moya.framework/Modules/Moya.swiftmodule/arm64-apple-ios-simulator.swiftinterface

final public class NetworkActivityPlugin : Moya.PluginType {
  public typealias NetworkActivityClosure = (_ change: Moya.NetworkActivityChangeType, _ target: Moya.TargetType) -> Swift.Void
  public init(networkActivityClosure: @escaping Moya.NetworkActivityPlugin.NetworkActivityClosure)
  final public func willSend(_ request: Moya.RequestType, target: Moya.TargetType)
  final public func didReceive(_ result: Swift.Result<Moya.Response, Moya.MoyaError>, target: Moya.TargetType)
  @objc deinit
}

//...

extension Moya.NetworkLoggerPlugin {
  public struct Configuration {
    public typealias OutputType = (_ target: Moya.TargetType, _ items: [Swift.String]) -> Swift.Void
    public var formatter: Moya.NetworkLoggerPlugin.Configuration.Formatter
    public var output: Moya.NetworkLoggerPlugin.Configuration.OutputType
    public var logOptions: Moya.NetworkLoggerPlugin.Configuration.LogOptions
    public init(formatter: Moya.NetworkLoggerPlugin.Configuration.Formatter = Formatter(), output: @escaping Moya.NetworkLoggerPlugin.Configuration.OutputType = defaultOutput, logOptions: Moya.NetworkLoggerPlugin.Configuration.LogOptions = .default)
    public static func defaultOutput(target: Moya.TargetType, items: [Swift.String])
  }
}

Sourcery fails with error:

SourceryRuntime/ParserResultsComposed.swift:151: Assertion failed: Type Moya.NetworkLoggerPlugin.Configuration should be extension
