Proc instead of String as error message doesn't work.

Description

Revision r48113 introduced Procs to delay time-consuming generation of error messages. This is a good idea, but it doesn't work for me.

How to reproduce: Make a small change in lib/unicode_normalize/tables.rb. Any change should do; I changed "Q" to "QQ" in one instance. Run make install(-nodoc). Run ruby test/test_unicode_normalize.rb.

The result I get is as follows:

===============================================================================
Failure:
test_normalize_to_NFKD_from_source_with_nfkd(TestNormalize)
test/test_unicode_normalize.rb:38:in `block (2 levels) in generate_test_normalize'
test/test_unicode_normalize.rb:33:in `each'
test/test_unicode_normalize.rb:33:in `block in generate_test_normalize'
#<Proc:0x000006033229f0@test/test_unicode_normalize.rb:32>
<"Q"> expected but was
<"QQ">

diff:
? QQ
===============================================================================

The failure is expected (artificially generated). The problem is the line
#<Proc:0x000006033229f0@test/test_unicode_normalize.rb:32>
The Proc that is supposed to be evaluated to generate a more detailed error message (showing codepoints of the characters involved) is just converted to a String.

For reference, I'm using the standard bundled gems minitest-5.4.1.gem, power_assert-0.1.4.gem, and test-unit-3.0.1.gem.
