MISC: attrs_parse() fixed error when multi-line value appeared

[patriki01]

When LDAP attributes values are too long, they split into multiple lines. It can look like the example provided, where originalDN is the problematic attribute:

# record 11
dn: name=ae3c2c8c-4b8f-11ee-ac71-c6e1a1a33042,cn=hbac_rules,cn=custom,cn=test,cn=sysdb
originalDN: ipaUniqueID=ae3c2c8c-4b8f-11ee-ac71-c6e1a1a33042,cn=hbac,dc=ipa,dc
 =test
serviceCategory: all

And this caused an error in attrs_parse() function. I added two tests to check this error, so look there for better understanding of the problem.
This is not a very nice solution, but I couldn't think of a better one. Feel free to suggest changes.

I improved the code and also added the test case you mentioned.
