Issue with Query Parsing

[StevenMMortimer]

rforcecom.query is generating an error when using the newer parser introduced in 97201d6 (#51). You can reproduce by installing from the following commit:

devtools::install_github('hiratake55/RForcecom', ref='2c1bd45715ca26c5fdb90f39e54a374916bd0675')

Run a simple query:

> session <- rforcecom.login(username = user, password = password,
+                            loginURL = url, apiVersion = apiVersion)
> query <- "SELECT Id, Account.Name FROM Opportunity"
> rforcecom.query(session, query)
Error: XML content does not seem to be XML: 'list("00661000005E3TsAAK")
list(Name = list("Express Logistics and Transport"))'

Not sure if this is related to package versions of httr, xml2, and/or purrr.
