Incorrect wrapping into a try/catch when having a directive

[maca88]

Example:

public class TryCatch
{
  public int Test()
  {
#if TEST
    var result = new Random();
    return result.Next() + 1;
#else
    var result = new Random();
    return result.Next();
#endif
  }
}

Expected:

public partial class TryCatch
{
  public Task<int> TestAsync()
  {
    try
    {
#if TEST
      var result = new Random();
      return Task.FromResult<int>(result.Next() + 1);
#else
      var result = new Random();
      return Task.FromResult<int>(result.Next());
#endif
    }
    catch (Exception ex)
    {
      return Task.FromException<int>(ex);
    }
  }
}

Actual:

public partial class TryCatch
{
  public Task<int> TestAsync()
  {
    try
    {
#if TEST
      var result = new Random();
      return result.Next() + 1;
#else
      var result = new Random();
      return Task.FromResult<int>(result.Next());
    }
    catch (Exception ex)
    {
      return Task.FromException<int>(ex);
    }
#endif
  }
}
