build(pom.xml): update H2 to 1.4.199

Changelog: http://www.h2database.com/html/changelog.html

Re-apply f087be3 commit.

Also fixes SQL query that have undetermined results:

%
In absence of ORDER BY clause rows don't have any specific order. Older versions of H2 produce row
with TRUE first, newer version of H2 produce row with FALSE first. Both behaviors are valid.
Non-standard LIMIT clause truncates the second row.
%

See for details: h2database/h2database#1874

This change makes migrations work on H2 1.4.198+

No functional changes.
