Only coerce scalars if ALLOW_COERCION_OF_SCALARS is enabled

[dansanduleac]

Fixes #69

This fix is for 2.9, but it should merge without conflicts into 2.10 as well.

Sounds reasonable; thank you for contributing this fix!

One request: would it be possible to add a matching unit test(s)? jackson-databind has a few tests to copy-paste, possibly:

src/test/java/com/fasterxml/jackson/databind/struct/ScalarCoercionTest.java

and it would be great to check against regression, as Afterburner's handling is quite fragile due to low-level nature of optimization.

@cowtowncoder do you think this is OK to merge now?

[cowtowncoder]

@dansanduleac Yes, I'd be happy to merge this. Just one more thing: unless I have asked for it (for any Jackson project), we need CLA. It can be found from:

https://github.com/FasterXML/jackson/blob/master/contributor-agreement.pdf

and usual way is to print it, fill & sign, scan, email. Normally I'd ask email to info at fasterxml dot com BUT unfortunately we are having some issues with that so if you can make it shareable some other way (can one attach document to a gist?), that'd be great.

As soon as I get that I'll go ahead and merge the patch. Once again thank you for submitting this & apologies for the hassle wrt cla.

@cowtowncoder not sure if I can add it to a gist, but if you give me some other e-mail address I can send it to, I'd be happy to!

[cowtowncoder]

@dansanduleac Actually info at fasterxml dot com works again, so use that.

CLA received, filed, merged the fix. Thank you! This will be in 2.9.9 (and 2.10.0+)
