Make test paths relative

[kortov]

fix this path

myexcel/src/test/java/com/github/liaochong/myexcel/core/BasicTest.java

Line 23 in 362bfcc

public static final String TEST_DIR = "/Users/liaochong/";

I've tried as
public static final String TEST_DIR = new File("").getAbsolutePath();

it works but all TEST_DIR + methods create files in IdeaProjects folder

maybe need add a path separator at the end
