bug: checkForTplFile checks wrong dir

[nguyening]

Ran into this issue trying to create a $GROUP.tpl which wasn't getting picked up. Also, adds rendering errors to the log message for more troubleshooting.

What I expected:

a = "base.tpl"
b = "mygrp.tpl"

What I got:

a = "base.tpl"
b = "default.tpl"

Script to reproduce:

set -x
go install github.com/pietdaniel/ddmon@942bb4c

mkdir monitors
pushd monitors

mkdir output
mkdir --parents resources/templates
echo 'a = "base.tpl"' > resources/templates/base.tpl
echo 'b = "default.tpl"' > resources/templates/default.tpl
echo 'b = "mygrp.tpl"' > resources/templates/mygrp.tpl

mkdir --parents monitors/data/myns/mygrp
touch monitors/data/common.yaml
touch monitors/data/myns/common.yaml
touch monitors/data/myns/mygrp/common.yaml
touch monitors/data/myns/mygrp/mymonitor.yaml

ddmon generate --source-dir ./monitors --target-dir ./output --template-dir ./resources/templates
cat output/mygrp-mymonitor.tf
popd
rm -r monitors
