feat(#889): Optimize Disassemble/Assemble Goals

[volodya-lombrozo]

In this PR I optimize disassemble/assemle goals to speed up development.

Timings after optimization:

[INFO]           spring-fat/pom.xml ............................... SUCCESS (301.7 s)
[INFO]           spring-fat/pom.xml ............................... SUCCESS (313.2 s)
[INFO]           spring-fat/pom.xml ............................... SUCCESS (378.5 s)

As you can see, in some cases we got ~ x10 speed up.

Related to #889.

@yegor256 Could you review these changes, please? I guess, eo repository has the same problems as well. It might be interesting for you.

@volodya-lombrozo looks good, but maybe it's better to fix the performance problem in the com.jcabi.xml.XMLDocument class?

[yegor256]

@volodya-lombrozo I can't understand where the performance gain is coming from? XMLDocument also encapsulates Node (not a String).

@yegor256 Sure, I left the ticket for it jcabi/jcabi-xml#277

@yegor256 It's an open question, we need to investigate it separately.
