Remove log of throwable in XC_MethodReplacement.java (#111)

Developers can get the throwable using the [XC_MethodHook.MethodHookParam API](https://api.xposed.info/reference/de/robv/android/xposed/XC_MethodHook.MethodHookParam.html).
Logging such throwable will leave unintended trace to the log buffer of the hooked application.

Note: this line of adding log was added in commit 7b638a706d
