Box SDK Update

[wadimw]

Updated Box SDK dependency to latest to fix connections over authenticated proxy.

Additionally, fixed Box SDK related tests DropServiceBoxTests, which got out of sync with filesystem DropServiceTests due to being @Ignored.

Test

1. In webapp/src/test/java/com/box/l10n/mojito/service/drop/DropServiceBoxTest.java:32 comment out annotation @Ignore. Build with ./mvnw clean install -DskipTests=true.

2. Create file $HOME/.l10n/config/webapp/application-test.properties and fill the following properties

   
   l10n.boxclient.clientId=
   l10n.boxclient.clientSecret=
   l10n.boxclient.publicKeyId=
   l10n.boxclient.privateKey=
   l10n.boxclient.privateKeyPassword=
   l10n.boxclient.enterpriseId=
   l10n.boxclient.appUserId=

l10n.boxclient.rootFolderId= l10n.boxclient.dropsFolderId=

according to this doc https://www.mojito.global//docs/guides/integrating-with-box/.

3. Create drop folder structure on Box (`mojito` > `Project Requests` as per https://www.mojito.global//docs/guides/integrating-with-box/) and fill properties `rootFolderId` and `dropsFolderId` accordingly.

4. Run

./mvnw test -Dtest='BoxAPIConnectionProviderTest,BoxSDKServiceTest,BoxDropExporterTest,BoxDropImporterTest' -DfailIfNoTests=false

4. Run

./mvnw test -Dtest='DropServiceBoxTest' -DfailIfNoTests=false

(this is a slow test ~7 min)
This test is running separately because it does some context stuff (see `@Ignore` annotation and mention of `@DirtiesContext`) which breaks BoxDropExporterTest for some reason. I don't know Spring enough to fix this right now, but at least it passes when run separately so I think it's fine.

@ehoogerbeets for some unknown reason in order to merge #979 I had to rebase it onto legacy - even though it was already on top it. This created duplicate commits and messed up this PR. Please re-approve
