'package-info.class' Verification Fails in PhPackage.java

[0pdd]

The puzzle 4717-b9941d0d from #4717 has to be resolved:

eo/eo-runtime/src/main/java/org/eolang/PhPackage.java

Lines 125 to 134 in 701b707

	* @todo #4717:90min Check 'package-info.class' existence before looking for an object.
	* Recently, we got an error when 'maven-compiler-plugin' removed 'package-info.class'
	* during compilation and we got quite confusing error message:
	* ```
	* Couldn't find object 'Φ.org.eolang.examples' because there's no class or package
	* 'EOorg.EOeolang.EOexamples' EOorg.EOeolang.EOexamples
	* ```
	* Having said that, the 'EOorg.EOeolang.EOexamples' package does exist.
	* The error tells nothing about missing 'package-info.class'. We need to check for the
	* existence of 'package-info.class' before trying to find an object.

If you have any technical questions, don't ask me, submit new tickets instead. The task will be "done" when the problem is fixed and the text of the puzzle is removed from the source code. Here is more about PDD and about me.
