Build fails in 'tp/tests': missing tests-parser.txt

[Hans-Bernhard Bröker]

Hello everyone,

Since roughly last week, the build of SVN texinfo fails in the tp/tests 
subproject, like this:

$ LC_ALL=C make
make: *** No rule to make target 'formatting/tests-parser.txt', needed 
by '../../../texinfo/tp/tests/Makefile.onetst'.  Stop.

I believe the 2018-09-15 change to rename these file didn't fully go 
through.  I found that several in tp still refer to tests-parser.txt 
files explicitly, although no such file is generated any more.

It seems a slightly more thorough global

        s/test-parser\.txt/list-of-tests/g

is needed to finish the job.
