blynk_for_chinese/more examples fail during library test

[jantje]

Describe the bug
To identify the library sloeber should not start from the full example path but from the examples folder.
This to support subfolders in the example folders

To Reproduce
run the CreateAndCompileLibraryExamplesTest.java test. (takes extremely long!!!)
The blynk_for_chinese/more examples will fail due to missing blynk_for_chinese library

note that create a new sketch based on blynk_for_chinese/more/formatString example
does work

Expected behavior
the blynk_for_chinese is available to the sketch
